This study examines the widespread socio-economic effects of climate change on food security in semi-arid areas such as Garissa County. Climate change has really posed a serious threat on food security in developing countries in Africa. This has made such countries to heavily rely on the foreign aid in form of food hand-outs to curb hunger. The shift in climatic conditions has stemmed up a lot of concern as whether Africa can feed itself and in this case, the Garissa County in Kenya. The past three decades have been characterized by an erratic rainfall pattern over Africa‘s sub-tropics and a significant decline in the amount of rainfall. This has actually resulted in droughts which have significantly affected agriculture and food production. The crops and livestock have failed to quickly adapt to the harsh climatic conditions. The research on the socio-economic impact of climate change on food security in Garissa shows that the county‘s agricultural sector is already suffering from the changing rainfall patterns, temperature increases and more extreme weather events, like the floods and droughts. Longer and more frequent droughts have substantially reduced the crop yields and this has negatively impacted food production in the county. The only way the Garissa County will be able to out-run the effects of climate change on food security would be to scale up production in the agricultural sector by setting up schemes to assist farmers so that they attain a maximum crop yields. These measures are analyzed, looking at their strengths and the shortfalls. This study takes an interesting turn as it analyses the social and economic impact of climate change and its ability to influence changes on the political landscape. The shortage of food and the depletion of water resources have a greater chance triggering the escalation of conflict which may influence the shifts in the county‘s balance of power.
